ClG'AR BUNCHlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 309,64a9, dated December 23, 188%.

Application filed January 23, 1884.

To all whom it may concern.-

Be it known that I, THOMAS E. Ronnu'rs, of Detroit, in the county of \Vayne and State of Michigan, have invented new and useful Improvements in Cigar-Enriching Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in the construction and operation of machines for bunching cigars; and the invention consists in the peculiar construction, arrangement, and combination of the various parts, all as more fully hereinafter set forth and claimed.

Figure 1 is a side elevation. Fig. 2 is a vertical. cross-section through the axis of the bunching-roller and its connections. Fig. 3 is a vertical longitudinal central section.

In the accompanying drawings, which form a part of this specification, A represents a suitable frame, in the sides of which are formed the ways I in which the anti-friction wheels 0 travel, such wheels being mounted upon axles D, the outer ends of which are rigidly secured to the bottoms of the standards E, the upper ends of which are connected together by a girt, F.

G- represents the bunching-roller, which is centered upon points H, tapped through the standards, and which receive jam-nuts I for securing thepoints to their adjusted position, allowing the roller to rotate freely upon them.

J represents the bunchingtable, which is concave upon its upper face in vertical crosssection in the direction of its length, and this table is provided upon its under face with downwardly-projeeting sockets K, which engage with the upper ends of the adjustingbolts L, tapped through the girts M of the frame.

N is the bunching-cloth, one end of which is secured to the rear girt, M, by means of the clamp-bar- O. The bunching-cloth thence passes up and over the bunching-table to and between the bunching-roller and the girt F, its end being secured upon. the rod P, which N0 model.)

is journaled in proper hearings in that end of the frame, and receives upon one end a thumb-nut, R, by means of which the rod is secured to its position and the depth of pocket formed by the bunching-cloth is governed. The forward end of the bunchingtable proper is depressed or bent downward- 5 5 ly, as shown at j, thus forming a depression into which the bunching-cloth may be pressed to form a pocket for the reception of the filler to be bunched, while cheeks S are secured to the frame by the set-screws s, so as to close the ends of the pocket so formed and to prevent the loss of tobacco in dropping out at the ends of the pocket. At the rear end of the bnnching-table I secure a bracket, T, which receives the bunch after it has been operated upon.

It will be observed that in this device the bunching-roller is a straight one, and that the swell or belly of the bunch is obtained by the concave surface of the bunching-table, and that this bunching'table can, by the means herein described, be raised or lowered as the work to be performed may require.

I deem it important that the table J be made adjustable to the roller instead of the roller to the table, as has been proposed, for by so doing I am enabled to adjust the table so as to get a greater pressure at one end of the table than at the other, and thus get a graduallyincreasing pressure from beginning to end of the reciprocation of the bunchingroller. This a very desirable feature, and one not attainable in a machine where the roller is adjusted to the bed.

hat I claim as my invention is- 8 5 1. In a cigar-bunching machine, a bunching-table concave upon its upper face in vertical cross-section, and means, substantially as described, for vertically adjusting said table, in combination with a horizontallyo traveling bunching-roller, substantially as herein set forth.

2. In a cigar-bunching machine, and in combination with the bunching cloth and roller thereof, the bunching-table J, provided on 9 5 its under face with sockets K, the girts M,

and the bolts L, passing through said girts and engaging with said sockets, substantially as and for the purpose specified.

3. The frame A, having grooved ways 13, in combination with the brackets E, connected at the top by the rod F and at the bottom by the bars D, extending from side to side and bracing said brackets, each of said bars D carrying an anti-friction roller at each end constructed to travel in said grooved 10 ways, substantially as and for the purposes specified.
